Alternatively (or additionally), if you want to demonstrate something on the command-line, you can do so as follows:

<cli>
lab46:~/src/unix$ head wildcard.notes
Their are a set of wild cards for your command line

* means 0 or more of any character (a true wild card);
so *.o would be any file that ends with .o

? - 1 of any character (a single wild card);
so ??? would be any file with 3 letters (so ls ??? would show any 3 letter files)

[] - 1 of any of the enclosed, so any of the letters entered in the brackets
so [rstlne] means it must have one of them to show, so ls [rstlne]* would only show
lab46:~/src/unix$
</cli>
